From 1-all at the outset, Swiatek seized complete control, collecting the next 11 games with her high-quality baseline game, rarely making an unforced error and repeatedly pressuring Pegula into mistakes.
Swiatek, a 22-year-old from Poland, went 5-0 at the tour’s season-closing championship, winning all 10 sets she played and ceding a total of just 20 games. That’s the fewest by the tournament’s winner since 2003, when it returned to a round-robin format; the previous low in that span was the 34 games dropped by Justine Henin in 2007.
She is also the youngest WTA Finals champion since Petra Kvitova was 21 in 2011, extending her winning streak to 11 matches and improving to 68-11 with six trophies in 2023, including at the French Open in June for her fourth Grand Slam title.
This victory allows her to return to No. 1, a spot Swiatek held from April 2022 until this September, when she relinquished it to Aryna Sabalenka. Swiatek defeated Sabalenka in a semifinal that began Saturday, was suspended by rain, then finished on Sunday.
Pegula hadn’t dropped a set entering Monday and eliminated her doubles partner, US Open champion Coco Gauff, on Saturday. Pegula, a 29-year-old born in New York and now based in Florida, was bidding to become the oldest first-time WTA Finals champ and to pick up what would have been the most important trophy of her career.
After beating No. 1 Sabalenka and No. 4 Elena Rybakina in the group stage, then No. 3 Gauff, Pegula’s matchup against No. 2 Swiatek made the American the first woman to face each of the top four players in the world at one event since the start of the WTA rankings in 1975.
But Pegula’s nine-match winning streak was stopped emphatically by Swiatek.
They played under a mostly blue sky and with far less wind than players were forced to contend with throughout the week. And, most importantly, there wasn’t a drop of rain.
The singles and doubles finals both originally were scheduled to be contested Sunday, then were pushed back a day after a series of showers during the week.
